[Dnsmasq-discuss] Detecting DHCP Requests from bridged interfaces

I have a bridged network interface, br0, which is made up of eth0 (my
internal LAN) and tap[0,1] (my bridged VPN adapters). dnsmasq listens
on br0 and handles DHCP for my network.
What I am wondering is if there is any means for dnsmasq to detect DHCP
requests from tap1 and handle them differently -- namely by not
supplying a default gateway.
It is my -- possibly limited -- understanding that ebtables can be used
to mark packets from one side of a bridge. If this is the case can
dnsmasq pick up on these marks and use them to affect behaviour?
